Point ClipEmber at a webinar recording and pick the window worth mining. It scores the whole window for hook strength — not only the opening — and renders captioned vertical clips, which is what makes slide-heavy sections still watchable on mute.
One recording holds dozens of shareable moments. ClipEmber finds the strongest takes, crops to the speaker and burns in captions people watch on mute.
Open the app to run it — 5 free videos every month, no card required.
Direct MP4 URL, YouTube link or a file upload up to 1 GB — screen-share and talking-head both work.
Every candidate moment inside the window you pick is scored for hook strength — start the window where the Q&A begins if that's the useful part.
Use the transcript editor to tighten a take, then queue posts to TikTok, Shorts and Reels.

Measured with six of our runs queued together, so these are loaded-worker times, not a quiet queue.
The clip this run ranked first opens on the presenter's own statistic — "only 15% of your workforce is truly engaged". That number is theirs, from the webinar; we are quoting the source, not measuring anything ourselves. What the run does tell you is where a webinar's strongest openers tend to sit: the speaker's numbers, not the introductions around them.
Request 7bce807c-bce6-4d64-bea4-d9ea8fe3b187 — every number above comes from that run, not from an average.
Yes — turn on Trim source and enter a start/end (mm:ss); only that window is considered.
Captions carry the value on slide-heavy sections; face-aware crop centers the presenter when they're on camera.
Typically 5 per request; each 20–90 seconds depending on your preferred length.
